2. 21. Thermal response test : numerical simulations and analyses

   Author : Anna-Maria Gustafsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

   Abstract : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. READ MORE

4. 22. Design of Thermal Barrier Coating Systems

   Author : Nicholas Curry; Per Nylén; Nicolaie Markocsan; Robert Vassen; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coating; Atmopsheric Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Thermal barrier coatings (TBC’s) are used to provide both thermal insulation and oxidation protection to high temperature components within gas turbines. The development of turbines for power generation and aviation has led to designs where the operation conditions exceed the upper limits of most conventional engineering materials. READ MORE

5. 23. Environmentally adapted lubricants : properties and performance

   Author : Anders Pettersson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Abstract : The lubricants of the future have to be more environmentally adapted, show a higher level of performance, and give a lower total life cycle cost (LCC) than the lubricants that are used today. One way to be able to produce, choose and formulate these lubricants is to have good knowledge about the properties of the base fluids and their additive response. READ MORE

6. 24. Thermal properties of bentonite based barriers : theoretical considerations and laboratory tests with special reference to the Buffer Mass Test in Stripa mine

7. 25. Design of Microstructures in Thermal Barrier Coatings : A Modelling Approach

   Author : Mohit Kumar Gupta; Per Nylén; Robert Vaβen; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coatings; microstructure; thermal conductivity; Young‘s modulus; lifetime; finite element modelling; design; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Plasma sprayed Thermal Barrier Coating systems (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. The material that is most commonly used in these applications is Yttria Stabilized Zirconia (YSZ) because of this ceramic’s favourable properties, such as low thermal conductivity, phase stability to high temperature, and good erosion resistance.
